2 Telephone book contains too many entries

The online telephone book may contain a maximum of 1000 entries. If you are using Google Contacts, the contact groups "My Contacts" and "Other Contacts" are both synchronized. The total number of entries in these groups may therefore not exceed 1000 entries.

3 Telephone book does not contain any telephone numbers

The FRITZ!Box only imports telephone book entries that contain telephone numbers. Since telephone books that only contain e-mail addresses are not imported, at least one entry must contain a telephone number.
